I have a custom scanning software using ntwain interface. I want to get all scanned images that scanner has scanned before I cancel transfer in TransferReady setting CancelAll to true.
When I cancel transfer it discards all pending data. Scanner is usually a few pages ahead, before I get them in my software. When I cancel scanning and scanner stops, I want to get all files that scanner has scanned before it stopped.
It is a problem because user must check which images were not scanned (they were discard by cancel) and then put them back in the tray.
